Assembly: mscorlib (in mscorlib.dll)
The RIPEMD160Managed type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | CanReuseTransform | Gets a value indicating whether the current transform can be reused. (Inherited from HashAlgorithm.) |
![]() | CanTransformMultipleBlocks | When overridden in a derived class, gets a value indicating whether multiple blocks can be transformed. (Inherited from HashAlgorithm.) |
![]() | Hash | Gets the value of the computed hash code. (Inherited from HashAlgorithm.) |
![]() | HashSize | Gets the size, in bits, of the computed hash code. (Inherited from HashAlgorithm.) |
![]() | InputBlockSize | When overridden in a derived class, gets the input block size. (Inherited from HashAlgorithm.) |
![]() | OutputBlockSize | When overridden in a derived class, gets the output block size. (Inherited from HashAlgorithm.) |
| Name | Description | |
|---|---|---|
![]() | Clear | Releases all resources used by the HashAlgorithm class. (Inherited from HashAlgorithm.) |
![]() | ComputeHash(array<Byte>) | Computes the hash value for the specified byte array. (Inherited from HashAlgorithm.) |
![]() | ComputeHash(Stream) | Computes the hash value for the specified Stream object. (Inherited from HashAlgorithm.) |
![]() | ComputeHash(array<Byte>, Int32, Int32) | Computes the hash value for the specified region of the specified byte array. (Inherited from HashAlgorithm.) |
![]() | Dispose() | Releases all resources used by the current instance of the HashAlgorithm class. (Inherited from HashAlgorithm.) |
![]() | Dispose(Boolean) | Releases the unmanaged resources used by the HashAlgorithm and optionally releases the managed resources. (Inherited from HashAlgorithm.) |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | HashCore | When overridden in a derived class, routes data written to the object into the RIPEMD160 hash algorithm for computing the hash. (Overrides HashAlgorithm::HashCore(array<Byte>, Int32, Int32).) |
![]() | HashFinal | When overridden in a derived class, finalizes the hash computation after the last data is processed by the cryptographic stream object. (Overrides HashAlgorithm::HashFinal().) |
![]() | Initialize | Initializes an instance of the RIPEMD160Managed class using the managed library. (Overrides HashAlgorithm::Initialize().) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | TransformBlock | Computes the hash value for the specified region of the input byte array and copies the specified region of the input byte array to the specified region of the output byte array. (Inherited from HashAlgorithm.) |
![]() | TransformFinalBlock | Computes the hash value for the specified region of the specified byte array. (Inherited from HashAlgorithm.) |
| Name | Description | |
|---|---|---|
![]() | HashSizeValue | Represents the size, in bits, of the computed hash code. (Inherited from HashAlgorithm.) |
![]() | HashValue | Represents the value of the computed hash code. (Inherited from HashAlgorithm.) |
![]() | State | Represents the state of the hash computation. (Inherited from HashAlgorithm.) |
The following code example shows how to encode a file using the RIPEMD160Managed class and then how to decode the file.
using namespace System; using namespace System::IO; using namespace System::Security::Cryptography; // Print the byte array in a readable format. void PrintByteArray( array<Byte>^array ) { int i; for ( i = 0; i < array->Length; i++ ) { Console::Write( String::Format( "{0:X2}", array[ i ] ) ); if ( (i % 4) == 3 ) Console::Write( " " ); } Console::WriteLine(); } int main() { array<String^>^args = Environment::GetCommandLineArgs(); if ( args->Length < 2 ) { Console::WriteLine( "Usage: hashdir <directory>" ); return 0; } try { // Create a DirectoryInfo object representing the specified directory. DirectoryInfo^ dir = gcnew DirectoryInfo( args[ 1 ] ); // Get the FileInfo objects for every file in the directory. array<FileInfo^>^files = dir->GetFiles(); // Initialize a RIPE160 hash object. RIPEMD160 ^ myRIPEMD160 = RIPEMD160Managed::Create(); array<Byte>^hashValue; // Compute and print the hash values for each file in directory. System::Collections::IEnumerator^ myEnum = files->GetEnumerator(); while ( myEnum->MoveNext() ) { FileInfo^ fInfo = safe_cast<FileInfo^>(myEnum->Current); // Create a fileStream for the file. FileStream^ fileStream = fInfo->Open( FileMode::Open ); // Compute the hash of the fileStream. hashValue = myRIPEMD160->ComputeHash( fileStream ); // Write the name of the file to the Console. Console::Write( "{0}: ", fInfo->Name ); // Write the hash value to the Console. PrintByteArray( hashValue ); // Close the file. fileStream->Close(); } return 0; } catch ( DirectoryNotFoundException^ ) { Console::WriteLine( "Error: The directory specified could not be found." ); } catch ( IOException^ ) { Console::WriteLine( "Error: A file in the directory could not be accessed." ); } }
